ARRL handbook would be the first place that I would look. Each year has different stuff in it. You may or may not find a 3cx3000 plan as it is more power than most would want, but you could find something to use as a starting point.
Keep in mind that you will need realistically a "bit" more than 5 watts to drive one, so you will need an intermediate amplifier as well.

You might find some schematics for a Henry 8k ultra. You better understand what you're doing if you build an amp like this. Small errors are expensive and there may be no second chance.
